2 Best APIs for Language filtering in Nigeria

NewsAPI is a widely-used news aggregation API that indexes articles from over 80,000 news sources worldwide, providing developers with a unified search interface for current and historical news content. The API crawls headlines, article metadata, and full content from newspapers, online magazines, broadcast news sites, and blogs, making it one of the most comprehensive news data sources available to developers. The Everything endpoint is the primary search interface. It accepts keyword queries with Boolean operators (AND, OR, NOT), source name filters, domain filters, language filters, and date range parameters. Results are sorted by relevance, popularity, or publication date and returned with title, description, content (truncated on free plan), URL, source name, author, and published timestamp. For a Nigerian business intelligence tool that monitors international news about the naira, CBN policy, or Nigerian stock market, the Everything endpoint's Boolean search capability enables precise topic monitoring that simple keyword matching would miss. The Top Headlines endpoint returns the current leading news stories by country, category, and source. The country parameter supports Nigeria (ng), making it possible to fetch top Nigerian news stories directly. Category options include business, entertainment, health, science, sports, technology, and general news. Nigerian news apps that want to surface trending stories automatically — without knowing the specific topics in advance — can use Top Headlines to build a dynamically updated front page. Source discovery lets developers retrieve a list of all sources available in NewsAPI's index, filterable by category, language, and country. This helps Nigerian developers identify which Nigerian publications are indexed (Punch, Vanguard, Premium Times, Guardian NG, TechCabal) and build source-specific collections that aggregate content from trusted Nigerian outlets. The free developer tier provides 100 requests per day with a 24-hour delay on news — suitable for prototyping and testing. Production applications serving real users require a paid plan, as the free tier's delayed content and low request limit are insufficient for live news applications. For Nigerian startups building news products, NewsAPI's paid plans represent a manageable infrastructure cost compared to building a custom crawler. The Everything endpoint's domain exclusion parameter allows developers to filter out specific news sources from results — useful for applications that want to exclude tabloid or unreliable sources from their aggregated feed. For Nigerian news applications building credibility, curating away known low-quality sources and featuring only established Nigerian and international publications improves the perceived trustworthiness of the content. This kind of editorial curation policy can be implemented entirely through API parameters rather than post-processing. The Articles object returned by NewsAPI includes a content field with the first 200 characters of the article body, giving enough context to understand whether the article is relevant without fetching the full article page. For high-volume monitoring applications, this brief content preview enables faster filtering — dismissing clearly irrelevant articles before making additional requests to retrieve full content. Nigerian monitoring tools processing hundreds of articles daily benefit from this two-stage retrieval pattern that reduces both processing time and bandwidth consumption. NewsAPI's response includes a totalResults count for each query, allowing Nigerian news apps to display result counts in search interfaces and implement efficient pagination by calculating total pages from the count divided by the page size parameter.

Currents API is a news data service that delivers the latest news articles from thousands of global and regional sources through a simple REST interface. Positioned as an accessible alternative to premium news APIs, Currents offers a generous free tier with 600 requests per day — enough for small-to-medium news applications to operate without initial cost — while providing reliable access to current news content across categories, languages, and regions. The Latest News endpoint returns the most recently published articles from Currents' source network, sorted by publication time. Each article object includes the title, description (article summary), content snippet, full article URL, author, publisher, publish time, image URL, and category tags. The structured metadata allows frontend applications to render consistent news card components without parsing inconsistent HTML from source pages. Nigerian news apps that want to display international headlines alongside local content can mix Currents API results with content from Nigerian-specific APIs. Keyword search provides full-text search across article titles and descriptions, with optional filtering by language, category, start date, and end date. Boolean operators are supported for combining terms. Monitoring tools that track specific topics — Nigerian election news, CBN monetary policy, Nigerian startup funding — can use keyword search to retrieve relevant articles as they publish. The date range filter makes historical research possible: retrieving all articles covering a specific Nigerian business event within a defined window for retrospective analysis. Category filtering organizes news into standard verticals: business, sports, technology, entertainment, health, science, and world news. For Nigerian news platforms that present content in organized sections, Currents API's category labels eliminate the need for custom classification logic — articles arrive pre-categorized. The category coverage aligns with the editorial sections typical of Nigerian news sites, making integration straightforward. Language filtering supports English (most relevant for Nigerian audiences) alongside Spanish, French, German, Portuguese, Arabic, and other major languages. For Nigerian platforms that serve the Nigerian diaspora in multiple countries or that target multilingual African audiences, language filtering enables serving appropriately localized content. The $9.99/month entry-level paid plan is accessible for Nigerian startups operating on lean budgets. The Currents API's health category covers medical and public health news globally, including health stories from Africa and Nigeria. For Nigerian health information platforms, aggregating health news through Currents provides a stream of articles about disease outbreaks, medication updates, health policy changes, and medical research developments relevant to Nigerian health audiences. The combination of health news from Currents with localized Nigerian health data creates comprehensive health information platforms that serve both general wellness and specific medical interests. Technology news from Currents includes startup funding announcements, product launches, and tech policy stories. Nigerian tech media outlets and startup ecosystem platforms that curate international tech news for Nigerian readers can use Currents' technology category as a content source. The sorting options — by date (most recent) or by relevance (best match to query) — let content curators choose between a chronological news feed and a relevance-ranked digest depending on their editorial approach.
